It's official! Climate alarmists are now even more alarmed…

I could provide other examples from the summary but the point is that the IPCC forecasts are based on the time-frame to 2100. Everything in it needs to be considered in that context, namely: we have 85 years in which to adapt to even the worst changes. The planet has NOT run out of time, contrary to what the Greens and sensationalist media want us to believe.

2. The IPCC represents a form of consensus science and, of course, science has never been consensual. It has always advanced knowledge through a process of debate and argument, the testing of hypotheses, observation and theory. Dissident scientists have often been proven correct over time against the wisdom and authority of the scientific establishment at a given point in history.

Personally, I am not a climate scientist and so I can accept that the consensus represented by the IPCC might be right, despite worrying criticisms that claim a flawed IPCC process. It may be that global warming is primarily driven by human industrial activity, by CO2 emissions. Beyond that, the consensus breaks down, but this does not stop the alarmists from using the IPCC consensus to justify every manner of exaggeration and hyperbole going way outside what the IPCC actually says. This is why I view with great caution people who insist that 'The Science is Settled' It certainly runs counter to my Marxist instincts based on old Karl's personal motto: "De omnibus dubitandum" – question everything!

So, the appeal to authority is not good enough for me in itself. The principal flaw of the IPCC methodology that concerns me is its emphasis on computer modelling. How have the models stood up against observed changes? Not very well, it would seem.

The IPCC's 2013 Assessment report admitted that the "historical simulations do not reproduce the observed recent warming hiatus". The hiatus – or absence of the expected significant increase in warming due to record levels of CO2 emissions – runs counter to the computer modelling. John Christy, a climatologist at the University of Alabama, and a former Lead Author for the IPCC, tested the outputs of 73 IPCC climate models against the facts observed through satellite and weather-balloon data from 1979 and 2013 and found that all the IPCC models ran hotter than the actual observed climate. Similar studies and findings can be accessed here.

3. The mainstream media portrays the oppositional views about climate change alarmism in terms of a conflict between the Right and the Left. Apparently it is left-wing to take an alarmist view and to see coal as evil. What utter nonsense!

My initial attraction to the Left 45 years ago was precisely because they were the ones talking about progress – or rather Progress (with a capital P). I would tag along with my father on Saturday mornings in the mid-1960s to visit the International Bookshop run by the Communist Party in Melbourne. He would meet a few of his like-minded workmates (from the factory in which he worked) there, and together we would marvel at the Soviet and Chinese propaganda magazines. What did we marvel at? Simple: all the pictorial examples of Progress – huge dams being built, new nuclear power stations, vast areas of land being cleared for food production or residential development. Just about everything that the Greens oppose.

Some readers will say that I was naive to fall for this propaganda. But the point is that that is what attracted me, and many others, to the 'red left' back then. It was not a value system based on ultra-conservative notions like 'Sustainability' but a belief that capitalism's profit motive and concentrated private ownership of means of production held back progress and that socialism was the way to unleash human creativity and productivity. I still believe that is the case, that we humans "ain't seen nothin' yet!".

I smirk to myself when I hear the current Australian Prime Minister, Tony Abbott, speak of plans to develop the north of Australia into a 'food bowl'. I first heard of that dream back in the 1960s from old veteran communists. They held it up as an example of what would happen under socialism – the centre of Australia would flourish through irrigation, they told me. Again, these were not 'green' values but truly progressive ones. The old blokes also assured me that such great development of the north of Australia would not happen any time soon under capitalism because there was no short-term profit to be made from it. I was maybe 16 when they told me that – I am now heading for 64. They were right.

Conclusion

For all the alarmism, greater alarmism and even greater alarmism, our two billion brothers and sisters who are hungry and do not have access to clean water will not do what some in the 'first world' would tell them and opt for less efficient and more costly forms of energy. In the industrialising and modernising countries of Africa, for instance, people will be lifted from extreme poverty – as the rest of us were – thanks mainly to fossil fuels. The only way to stop this process is by developing energy sources that are cheaper and more efficient than coal. But people are hungry right now. And coal is cheap, and efficient.

Another value that attracted me to the left in my youth was the sense of confidence in humanity – and that meant, and means, confidence in the future. Without that confidence, why bother?
